Method and apparatus for producing energy using air pressure differential

ABSTRACT

An apparatus for generating and a method for creating the apparatus are disclosed. In an embodiment, the apparatus comprises an element (e.g., a mountain) having a conduit formed therein. The conduit has an inlet and an outlet, with the inlet disposed at a first elevation and the outlet is disposed at a second elevation higher than the first elevation. A generator is disposed in the conduit such that fluid moving through the conduit motivates the generator.

FIELD

The embodiments disclosed herein relate generally to energy production, and more particularly to using pressure differential of a fluid to produce energy.

BACKGROUND

Wind is caused by air moving from an area of high pressure to an area of low pressure. This naturally occurring flow of air has been harnessed for centuries in order to accomplish various useful functions. For example, windmills were originally used to accomplish mechanical functions such as grinding and pumping water. Eventually windmills were used to generate electricity by coupling a generator to a rotating portion of the windmill.

In order to increase the amount of energy produced, wind-harnessing devices are usually placed in areas where the wind blows the strongest and the most frequently. However, one drawback of positioning wind-harnessing devices along the surface of the earth is that in most areas the wind does not always blow with enough force to generate electricity. This is due to the fact that the pressure differential along the surface of the earth is usually changing. Thus, a wind-harnessing device in a fixed position on the surface of the earth is only effective when the pressure conditions along the surface of the earth are suitable to generate a flow of wind that can motivate a generator.

SUMMARY

An apparatus for generating energy and a method for creating the apparatus are disclosed. In an embodiment, the apparatus comprises an element (e.g., a mountain) having a conduit formed therein. The conduit has an inlet and an outlet, with the inlet disposed at a first elevation and the outlet is disposed at a second elevation higher than the first elevation. A generator is disposed in the conduit such that fluid moving through the conduit motivates the generator.

In one embodiment, a furnace is disposed within the conduit to heat the fluid flowing through the conduit to increase the velocity of the fluid flow. In another embodiment, a radiator is disposed in the conduit so that the fluid flow can cool the radiator.

In various embodiments, the inlet of the conduit has a larger cross-sectional area than the cross-sectional area of the outlet. In an alternative embodiment, multiple conduit branches, each having a separate inlet, converge to feed the outlet.

DETAILED DESCRIPTION

In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various embodiments. It will be apparent to one skilled in the art that the embodiments may be practiced without some of these specific details.

The following description and the accompanying drawings provide examples for the purposes of illustration. However, these examples should not be construed in a limiting sense as they are not intended to provide an exhaustive list of all possible implementations. In other instances, certain structures and devices are omitted or simplified in order to avoid obscuring the details of the various embodiments.

Referring now to FIG. 1, a flow chart is shown that details a method of creating an apparatus capable of generating energy. At block 40, a conduit is formed in an element. The element could be, for example, a man-made structure, a portion of the earth, or vegetation on the earth.

The conduit has an inlet and an outlet. At block 42, the inlet is positioned at a first elevation within a body of a fluid. The body of fluid is at least one of a gas and a liquid. In some embodiments, the body of fluid is simply air from the atmosphere. In other embodiments, the body of fluid could be water.

At block 44, the outlet of the conduit is positioned, for example, at a second elevation that is higher than the first elevation. The reasoning for positioning the outlet at a higher elevation is that the pressure at the higher elevation is presumably lower than the pressure at the first elevation, which causes fluid to flow from the inlet to the outlet. However, the inlet and outlet may be positioned in any manner to take advantage of a pressure differential and/or a temperature differential that yields a flow of fluid from the inlet to the outlet.

A generator is disposed in the conduit, at block 46, such that fluid moving through the conduit motivates the generator. Although a generator is used in this embodiment to generate energy or electricity, any device could be disposed in the fluid path to take advantage (e.g., mechanically or electrically) of the moving fluid.

FIG. 2 shows an example of a device created according to the method described in regards to FIG. 1. Element 10 is a mountain in this embodiment. Conduit 12 is formed in element 10 and has inlet 14 disposed at a first elevation on one side of element 10 and outlet 16 disposed at a second elevation on a different side of element 10. The second elevation is higher than the first elevation. Presumably, air moves from inlet 14 to outlet 16 due to at least one of a pressure differential and a temperature differential.

Generator 18 is disposed in conduit 12 such that the flow of air through conduit 12, indicated by arrows in FIG. 2, motivates generator 18. Although generator is disposed near outlet 16 in FIG. 2, generator 18 may be disposed at any position within conduit 12, including near inlet 14.

FIG. 3 shows an alternative embodiment wherein conduit 20 has inlet 14 positioned at a first elevation on one side of element 10 and outlet 16 positioned at a second elevation at the top of element 10.

FIG. 4 shows a further embodiment wherein conduit 22 has inlet 14 positioned at a first elevation on one side of element 10 and outlet 16 positioned at a second elevation on the same side of element 10 as inlet 14. FIG. 4 also has furnace 24 disposed in conduit 22. Furnace 24 heats the fluid flowing through conduit 22 to increase the velocity of the fluid flow. Although furnace 24 is disposed near inlet 14, furnace 24 may be disposed anywhere within conduit 22. Moreover, furnace 24 may be used in conjunction with any of the other embodiments disclosed herein.

FIG. 5 shows an embodiment having a plurality of conduit branches 26. Conduit branches 26 converge to feed outlet 16. Each conduit branch 26 has a separate inlet 28. Inlets 28 are disposed at elevations lower than the elevation of outlet 16. Such a configuration increases the volume of fluid flow to motivate generator 18.

Radiator 29 is disposed where conduit branches 26 converge. Radiator 29 is, for example, at a temperature higher than that of the fluid flowing through conduit branches. Thus, the fluid flow cools radiator 29 and is heated by radiator 29, which increases the velocity of the fluid flow. Although radiator 29 is shown in the area where conduit branches 26 converge, radiator 29 may be disposed anywhere within conduit branches 26 of FIG. 5 or at any point within the other embodiments disclosed herein.

FIG. 6 shows an embodiment wherein inlet 30 of conduit 34 has a larger cross-sectional area than the cross-sectional area of outlet 32. The embodiments shown in FIGS. 2-5 may have inlets and outlets with the same cross-sectional area or may have a difference in cross-sectional area, as shown in FIG. 6. Despite the relative cross-sectional areas of the inlet and the outlet, the inlets and outlets of the various embodiments may have any shape that allows fluid flow through the conduit to motivate generator 18.
